Abstract：Objective To evaluate the feasibility and clinical effects of surgery under percutaneous spine endoscope in single segmental cauda equina injury caused by the protrusion of the lumbar disc.Methods Ninety-six patients with cauda equina injury caused by the protrusion of the lumbar disc from January 2011 to August 2013 were retrospectively analyzed. Sixty-nine among them were operated under percutaneous spine endoscope. Visual analogue scale ( VAS ) was assessed preoperatively and during the lastest postoperative follow-up. Clinical efifcacy was evaluated by Nakano standard in the lastest follow-up.Results Sixty-six patients ( male 38, female 28 ) were followed up. The median follow-up time was 16 months ( range: 9-36 months ). The preoperative VAS score of leg pain was 7.68±1.12. The mean VAS score of the lastest follow-up for leg pain was ( 1.01±0.81 ) points. The mean preoperative VAS score of back pain was 7.51±1.21. The mean VAS score of the lastest follow-up for back pain was 1.63±1.42. Differences were statistically signiifcant (P<0.05 ). Clinical efifcacy was assessed by Nakano rating in the lastest follow-up: excellent 23, good 21, improved 18, poor 4. Three months postoperatively, MRI showed good decompression of the oppressed nerves and complete removal of the herniated nucleus pulposus.Conclusions Percutaneous spine endoscope technique is an ideal method for minimally invasive surgery in the treatment of single segmental cauda equina injury caused by the protrusion of the lumbar disc, which could completely remove the herniated nucleus pulposus and achieve satisfactory clinical effects.
